The ability to simulate theBond workindex test also allows examination of truncated ballmillfeed size distributions on theworkindex. For grinding circuits where the feed to a ballmillis sent directly to the classifier and the cyclone underflow feeds the ballmill(see Figure 3.10), a question arises as to whether this practice will alter the ballmill workindex (BW i) of the material ...
This Grindability Test orBondBallMill WorkIndex Procedure is used to determine theBond WorkIndex of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a BallMillusing a standard ball charge. Below describes in general terms theBond WorkIndex Procedure used by a Professional Metallurgical Testing Laboratory. If you ...Get Price
The FCBond WorkIndex Test BallMillwas designed by F. C.Bondfor use in determining theBondIndex, a measure of grindability and power required for grinding applications. The FCBondMills are used in laboratories throughout the world. A copy of Fred C.Bond’s Method of Crushing and Grinding for determination of theBondIndex is included with eachmill.Get Price

BondRodMillGrindability Test. Grinding Solutions can carry outBondRodMill WorkIndex tests to determine the energy requirements for milling ore in a rodmill. The test requires a minimum of 20kg of -12.5mm material. Closing screen sizes typically range from 4.75mm to 212µm. Abrasion Index TestGet Price
BondRodMillGrindability Test. The test determines theBondRodMill WorkIndex which is used withBond’s Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied. The test is a closed-circuit dry grindability test performed in a standard rodmill.Get Price
Bondrodmill workindex results from Australian laboratories with smooth liners should not be used in the SAGMILLING.COM models. The test is a 'locked-cycle' test where ground product is removed from test cycles and replaced by fresh feed. The test must achieve a steady-state before completion.Get Price
